土壤-生物炭固碳减排潜力的核算方法
By measuring the CO2, CH4, and N2O emission fluxes from soil and biochar using the static box method and combining this with the warming potential weighting, the cumulative carbon sequestration and emission reduction potential of soil is calculated. This solves the problem of the difficulty in accurately assessing the carbon sequestration and emission reduction potential of soil-biochar in existing technologies, and achieves simple, accurate quantitative assessment and large-scale application.

AI Technical Summary
Existing technologies have failed to accurately assess the carbon sequestration and emission reduction potential of biochar in soil, and lack quantifiable standardized indicators, making it difficult to simply and accurately assess the carbon sequestration and emission reduction potential of soil-biochar under different conditions.
A static chamber method was used to conduct a simulated cultivation experiment to measure the CO2, CH4, and N2O emission fluxes from the soil and the added biochar. The cumulative carbon sequestration and emission reduction potential of the soil was calculated by combining the warming potential weight. The concentration change rate was corrected by the standard gas molar volume coefficient to estimate the actual carbon sequestration and emission reduction potential of the soil-biochar system at any time.
Accurate estimation of the carbon sequestration and emission reduction potential of soil-biochar systems without the use of isotope tracing technology simplifies and quantifies complex problems, providing a scientific basis to promote the precise application and large-scale industrial application of biochar under different environmental conditions.
